Jolly Logic AltimeterOne

How high did that rocket fly? Using the AltimeterOne is the easiest way to find out. Just latch it on the bottom of the nose cone, and launch it. The LCD readout tells you exactly how high the rocket flew by measuring the air pressure when the rocket reaches the peak altitude. It’s accurate, easy-to-use, and works great with students and is perfect for science fair projects. Also works with kites, balloons, falconry, quad-copters and model airplanes. Weighs only 9.9 grams, so it hardly affects the performace of the model rocket at all.
